Yes, they wouldnt be proper tests but mdma has a certain sweet aniseed type smell and a nasty bitter taste
Honestly haha, I know it's stupid & irresponsible , but my way of testing pills is just biting into them, tasting the insides, swallowing it, and seeing what the high is like.
The only exceptions of course is when I taste meth, then I spit it out. I'd never go back to that shit, even if it was just a small amount in a pill.
